Transoceanic 4 × 4 Gbit/s system combining dispersion-managed soliton transmission and new ‘black-box’ in-line optical regeneration

An exact analytical solution is derived for the variance of the timing jitter of a dispersion-managed soliton in the presence of synchronous amplitude modulators and filters. We show that, for a given position of these control elements, a total suppression of the timing jitter is possible, which will permit unlimited error free transmission distances of DM solitons. However, if only the modulator or the filter is used, the asymptotic behavior of the timing jitter shows a linear dependence with distance, which is in contrast with the cubic dependence in the uncontrolled case.

“…Some recent examples of applications of optical solitons in these areas include all-optical regeneration using conversion of return-to-zero (RZ) signals into conventional solitons 8,9 and all-optical picosecond-pulse packet buffers based on four-wave-mixing loading and intracavity soliton control. 10 It was shown in Refs.…”

“…For example, in the optical regeneration technique, a standard chirped-RZ signal (well approximated by chirped Gaussian pulses) is converted into the NLSE soliton for efficient filtering and then launched again into the fiber line. 8,9 Also it is a known fact among the experimentalists that it is quite difficult to control the chirp for sech-shaped input pulses. Therefore if one tries to produce supersoliton inputs N sech t with large N, the chirp becomes uncontrollable and difficult to quantify.…”

Conversion of a chirped Gaussian pulse to a soliton or a bound multisoliton state in quasi-lossless and lossy optical fiber spans

The formation of single-soliton or bound-multisoliton states from a single linearly chirped Gaussian pulse in quasi-lossless and lossy fiber spans is examined. The conversion of an input-chirped pulse into soliton states is carried out by virtue of the so-called direct Zakharov-Shabat spectral problem, the solution of which allows one to single out the radiative (dispersive) and soliton constituents of the beam and determine the parameters of the emerging bound state(s). We describe here how the emerging pulse characteristics (the number of bound solitons, the relative soliton power) depend on the input pulse chirp and amplitude.

“…Ref. [8] studied the transmission of the dispersion managed soliton (DMS) in WDM system, one kind of soliton regenerators was placed periodically along the fiber link, which consists of two sections; the first section utilizes the synchronous phase modulator (PM) and high dispersive fiber to reduce timing jitter, and the second section is composed of a frequency guiding optical filter and an intensity modulator (IM). The DMS is transformed to the standard Schrödinger soliton at the first section, and then transformed back to DMS at the second section in the regenerator.…”

A novel fiber optical 3R regenerator based on optical soliton-effect using highly nonlinear fiber is constructed and investigated for the needs of the high rate and long-haul optical communications. The propagation equation of the pulses in the proposed optical 3R regenerator with the control of optical modulator and filter is established. By the use of the variational approach, the evolution of the distorted optical pulses in the regenerator and the functions of reamplification, reshaping, and retiming are investigated. The relation between the construction parameters and the output performance of the regenerator is discussed. The stable operation condition of the regenerator is revealed. optical regenerator, optical soliton, high nonlinear fiber, optical amplitude modulation, analysis of stability
